Background:
ARL15(ADP-ribosylation factor-like protein 15) is also named as ARFRP2(ADP-ribosylation factor-related protein 2) and belongs to the small GTPase superfamily and Arf familiy.ADP-ribosylation factor-related protein (ARP) is a membrane-associated GTPase with remote similarity to the family of ADP-ribosylation factors (ARF)(PMID:10092663). Arl15 is present in chordates but not lower eukaryotes. Arl15 lacks a site for Nmyristoylation, but the N-terminal region contains several well-conserved cysteines, suggesting that it may bepalmitoylated(PMID:17506703).
